A prolonged illness of any kind will of course put immense strain on family members, and while there is sometimes temptation to end the suffering of a loved one, there is no excuse to go against their wishes to keep fighting.

Now, Chicago PD have opened up an investigation against the wife of the late singer for just that.

In life, Dennis and Brenda were married for over 18 years, living together in Illinois right up until the tragic death of the singer.

They moved to Chicago in order to have better access to medical aid as his condition deteriorated.

Now, court documents show that a protection order request was filed on behalf of the signer only weeks ago after abusive behavior from his wife was reported.
